T alien/m it may concern, I

j Be it'known that 1, WILLIAM GAIL'oR,

a citizen of the United States, residing at Saratoga' Springs, in the countyof Saratoga and State of New York,"-have invented certain new and useful Improvements in Roller Attachments for Power-Driven Ma- 'chines, of 'which the following isa specifica non.

. such manner that the roller will support power of the motor will be transmitted from said rear end, with the traction wheels of the vehicle raised from the ground, and I provide driving connections between the traction wheels of the vehicle and theroller, whereby when the motor is operated the the traction wheels to the roller, which then serves as a traction wheel to drive the vehicle. As the weight of the rear part of the vehicle rests upon the roller, the pressure of the latter upon the roadway or lawn may be increased as desired by loading. the vehicle moreor less.

In the accompanying drawing,

Fig. 1 is a side elevation of the rear portion of a power driven vehicle having my improvements thereon;

Fig. 2 is a rear end elevation of the same, partly broken away; and,

Fig. 3 is a sectional detail of one of the sprocket wheel attachments for the traction wheels. I

Referring to the drawing, a represents. a motor operated truck, comprising the chassis frame 1, body 2, and rear or traction wheels 3. The rear axle housing is indicated at 4, the propeller shaft at 5, and 6 represents one of the radius rods connecting the rear axle housing with the frame.

Upon the rear ends of the side bars of the chassis frame, I provide laterally extending brackets 7, each having bearings 8 and 9 for a shaft 10. Collars l1, securedto the shaft adjacent the outerbearings 9, prevent endthe draw bar is secured by a set screw 19. Each draw bar'is made in two parts, c and isshown in two section's, and b?,'wl1ich are independently revolubleon the shaft 13, and each sectionis provided; with a sprocket wheel 14, rigidly-securedto 'itinany-' nitable ma-nner. Upon each traction wheelof the 'vehicle 'is bolted a sprocket wheel 15,

and driving chains 16 extend around the sprocket wheels on the tractiOn WheeIsand on the roller sections. The sprocket wheels 15 are provided with'flan'ges 15, by which they maybe bolted to the traction wheels by thesame bolts-"l7 'which connect the. wheel hubs to the spokes, and sazid sprocket wheels. are provided "with outwardly extend I ing hubs 1 5 to whichdraw bars 0 areccon nected. As'showmea'ch draw bar'has asplit bearing 18 at one end fitting within a recess 15 in the sprocket wheel hub, and the opposite end of the draw bar has an opening to receive the" shaft 13 of the roller to which 0 the former provided with longitudinal 2 slots 20, andthe latter providedwith bolts 2 21 which extend through said slots, the arrangement being such that the draw bar may be lengthened or shortened by moving one part with respect 'to'the. other and then tightening the bolts. This adjustment is provided in order to take up the slack inthe drive chains as'the chains and sprockets wear. As will be noted from the drawing, when the roller attachment is applied to the vehicle, the roller supports the rear-end of the vehicle and also serves as a traction means, thetraction wheels of the vehicle being raised from the ground. In order to support the rear axle and traction wheels, I provide at each side of the chassis frame a sling 22, which extends beneath the rear axle housing and is connected at one end to a bracket 23 and at its opposite end to a threaded bolt 24, which extends through a right angle projection 23 on said bracket. The bolt is provided with a nut 25 by which the bolt maybe raised or lowered to tighten or loosen the sling. These slings sustain the weight of the axle when the rear of the ve- 1 hicle is sup-ported by the roller;

When the parts are connected as shown in the drawing, it will be evidentthat the. power transmitted'to the driving wheels of, the vehicle from the engine will betransmitted from said wheelsto the roller. When the roller is drivenyin one direction or the 11 v other, the vehicle will be pulled or pushed by the roller through the medium of the draw bars. g Y

The attachment may be applied to light or heavy commercial vehicles, according to the work to be performed, and the weight on. the roller may be varied by varying the load on the vehicle. In many cases, for repair work on roads, a vehicle equipped with this attachment may be used instead of a regular road roller. For operating on lawns, the attachment is desirable since the vehicle wheels are raised from the ground and cannot score the lawn.

What I claim is: v

1. The combination with a motor vehicle having a chassis frame, a rear axle and traction wheels, of a roller at the rear of said wheels and havinga shaft, links suitably connected to the chassis frame and to said shaft and adapted to support the frame, drawbars connecting said axle with said shaft, driving connections between said axle and shaft, and means for supporting said traction wheels from the chassis frame.

'2. The combination with a motor vehicle having a chassis frame, arear axle and traction wheels, of a shaft extending transversely of said frame at the rear of said wheels, a road roller having a shaft, links connecting said shafts and adapted to support said frame, drawbars connecting'the road roller shaft with the hubs of the traction wheels, driving connections between said hubs and said latter shaft, and means for raising the traction Wheels from the ground.

3. The combinationwith a motor vehicle having a chassis frame, a rear axle and traction wheels, of sprocket wheels secured to the traction wheels and having hubs, a roller at the rear of said traction wheels and having a shaft, sprocket wheels on said shaft, draw bars connecting said hubs and shaft, driving chains extending around the 1 sprocket wheels on the hubs and shaft, links depending from the chassis frame and connected to said shaft, and means for support.

ing the traction wheels from the chassis frame.

In testimony whereof I affix my signature.

WILLIAM H. GAILOR.
